Nitin I am posting the code snippet here
POIFSFileSystem newDoc = new POIFSFileSystem();
POIFSFileSystem poifs = new POIFSFileSystem(new FileInputStream(new
File("fileName")));
for(Entry entry : poifs.getRoot()){
if(! entry.getName().startsWith(AttachmentChunks.PREFIX)) {
EntryUtils.copyNodeRecursively(entry, newDoc.getRoot());
}
}
File fToWrite = new File("C:/CR0040POC/detachedMail/"+msgFile);
OutputStream out = new FileOutputStream(fToWrite);
newDoc.writeFilesystem(out);
out.close();

What do you mean by an eml? I can think of several different formats that
have all been known to use that file extension...

okay, thanks
Can you also let me know if the same is also possible when the file format
is .EML?
That mean when .EML have several attachments which need to be removed and
save the .EML file without any attachment?

Yes, but you'll have to write some code yourself. See my email for details
of the building blocks you'll want to use

You'll want to do a filtered copy of the POIFS. Either iterate through the
nodes and pick yourself which to copy and which not to, or just something
like FilteringDirectoryNode
<http://poi.apache.org/apidocs/org/apache/poi/poifs/filesystem/FilteringDirectoryNode.html>
when you do it. EntryUtils
<http://poi.apache.org/apidocs/org/apache/poi/poifs/filesystem/EntryUtils.html>
should help you with the copying
See http://poi.apache.org/poifs/how-to.html for more on POIFS. Use
HSMFDump
<http://poi.apache.org/apidocs/org/apache/poi/hsmf/dev/HSMFDump.html> to
help you work out which bits to copy, and which bits to ignore

The attachments could be .MSGs or any other file like .doc, .xls etc.
I am unable to save the original .MSG file without the attachments. Multiple
warnings can be included if it is not possible without the warnings.
Does POI also supports .EML format?

What kind of attachments - other msg files, or anything else? (The
outlook file format stores other messages in a totally different way to
all other attachments)
And how many warnings can you put up with in Outlook when the
attachments have been removed?
